Application led une 23, 1915. Serial No. 35,742.

Acitizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have invented a new and useful Metallic Window, of which the following is a specification.

My invention relates to a new and useful metallic window and consists in providing. means for assembling and securing the parts together whereby the window can be sent in knock-down condition and set up in the window openings' of a. building.

lt further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, l have shown in the' accompanying drawings one form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my inventionis not limitedj to the precise arrangement and or ganization of these instrumentalities as l herein shown and described.

on an enlarged scale, showing the manner of connecting the division bar therein. Fig. 11i is a front elevation of a complete window frame and sashes on a reduced scale. Similar numerals of reference indicate corresponding parts' in the figures.

Referring to the drawings, 1 designates the sill of the window frame which is formed of sheet metal of a single piece and which is suitably bent to form vertical walls 2 and 3 having the inwardly turned flanges L at the bottom which are adapted to rest on the bottom wall 5 of the window opening, the upper wall of the sill being bent to ferm the top surfaces 6 and 7 which, as here shown, are on di'erent levels formed by bending the metal at 8, the bottom of the window-frame sashesI contacting with these surfaces at theI proper time, as will be evident. It willbe understood that the sill extends across the window opening with the ends thereof seated in suitable recesses 9 formed in the wall 10 of the window opening. Suitably secured to the sill adjacent each end thereof is a metallic plate 11 which, as here shown, basan end flange 1Q extending upwardly therefrom and the side flanges 13 and'll, said plate being secured to the sill by the screws 15, by which means it will be understood that the said sill is provided with upwardly extending flanges, as will be evident.

In contact with the sill are the jambs 16v of the window-frame only one of which is illustrated, see Fig. 3, and as here shown each jamb is formed of sheet metal bent to form the end walls 17 and 18 and with the ends of the metal bent inwardly to form the ing the jamb is bent at the opposite or outer side to provide the shoulders 2O and 21 and a division-strip 22,I extending out- Ywardly intermediate the shoulders'20 and21 at substantially the central portion of the jamb in order tof'form the runways 23 and 24 for the window-frame. The inner walls Y25of the runways are suitably positioned adjacent the flanges 13 and 14 and are se- YThe end flange 12 of the cured thereto ina suitable manner lin order that the jambs will be properly connected' with the sill.

As here shown, I have connected the in ner wall of the runway with the flanges by screws 26 which pass through suitable openings punched inthe flanges, the metal struck from the openings forming threaded bosses 27 with which thescrews 26 engage.

plate 11 isconnected with the endwall 18 of the jamb by a screw 28 which is' in similar engagement with a threaded boss 27 thereon. The lintel 0r head 29 is formed of sheet metal and of a single strip of material bent to form the outer walls 30 and 3'1 having the inturned .portions 32 and with its bottom bent/to 25' form shoulders 33 and 34 with a division strip 35 therebetween thusforming suitable pockets for the reception of the window sash frames.

The upper edges of the jambs 16 abut the bottom wall of the-head 29 and thelatter is provided with a slot 36 adjacent each oint of contact. In order to connect the jamb -15 and head 29, I provide a pulley 'l housing 37 which is formed of a U-shaped portion 38 having bearings 39 for the journals of the sash pulley 40 and one side of which housing is provided with afiange 41 By this means it will be understood that the sill canv be placed in position in the window opening after. which the jambs are inserted in the side recesss resting upon the sill'and are secured to the flanges of the plate 11 which are secured to the sill and thereafter the head or top can be se' cured to thejambs by means of the pulley' housing just described.

In lthe construction of wherein two pairs or more of sashes are desired,.I employ a mullion and for this uro`se I connect a plate 45 with the sill 1,

intermediate the end plates 11, by means of s screws 46, said late having an end ange 47 and pairs o flanges "48 and 49 on the opposite sides thereof extending upwardly therefrom, as seen in Figs. 3 and 7, each of the flanges havingv an opening 50 therethrough and with the metal, struck up from the openings, forming bosses 51 and to the flanges of this plate I connect the mullion.

As here shown, the mullion comprises a body portion formed of a single piece of sheetl metal, bent to form an end wall 52 having adjacent thereto the outwardly extending shoulders 53 on opposite sidesl of the body 'and with the metal bent inwardly to form pockets 54 and the extending end portions 55, the said pockets 54 being formed on opposite sides adjacent the center of the mullion. The body portion can be slipped or slid on to the flanges of the plate 45 and can be secured to the same by screws 56 the flange 47 being secured to the end wall 52 and the side flanges to the sides 'of the mullion body in order that the said body'portion of the mullion will be suitably vsecured to the sill. lThe upper ends of the sides of the mullion abut the head 29 which is provided with suitable slots similar to slots 36 adjacent the pointl of contact of the said side walls and a Ipair of pulley housings' 37 will be suitably connected with the head by thelange 44 and each is provided with a flange 42 extending downwardly through a slot 346 of the head, to be connected each with a side wall of the body of the mullion. From this it will be understood that the mullion is connected with the head in a similarimanner to the connection of the jambs and head.

- Removably secured within the pockets 54 are the division strips 57 formed of' metal bent Ug-shaped and which project suliciently beyond the pockets to form run ways and to engage the side walls of the Window-frame Sashes. As here shown, I have connected the division strips by screws 58 which pass through suitable openings in the inner wall 59 of the pocket and a nut 60 is engaged with the threaded end of the screws 58 for holding the same in position. In order to lock the nuts against movement, I have provided a cup 61, see Fig. 10, which is provided vwith the side walls 62 and with the flanged walls 63, the cut being formed from a blank, as shown in, Fig. 9, and being suitably bent along the dotted lines, as will be evident. The base 64 of the cup 61 is provided with an opening 65 through which the ends of the screws 58 project. The inner walls 59 of the pockets of the mullion are provided with suitable slots 66 into a metallic wmdow.

which the langes 63 are inserted after the nut is tightened and the ends of the flanges are bent to engage the inner side of the said inner wall 59 thus serving to lock thev nut against movement. Removably secured to ythe ends 55 of the body of the mullion is a removable'rim or cover 67 which is formed of sheet metal suitably bent to provide thev walls 68 on each side of the body portion which form shoulders and which, with the division strips 57 ,form a runway for one window sashframe, while shoulders 53 and strips 57 form a runway for the other window sash frame. In order to removably connect the cover 6 7 the ends of the members 55 of the mullion body are provided with an opening 69 and with the slots 70 and a screw 71 having its head in engagement with a suitable portion of the removable cover passes through the opening 69 and is engaged by a nut 72 whichlvis held against movement by a cup 61 similar to that previously described. From` this it will be understood that the mullion is secured to the flanges of the plate 45 at the building and after the outer sash has been placed in position the division strips are secured to the mullion after which the inner window sash is placed in position and the cover 67 is then secured in p laee by which means the partscan be readily assembled, as will be evident. y

It will'be noted that the connection of the body of the mullion to the flanges of the I plate 45 is made at the inner walls of the engaged with the threads of the bolt to lock ders 79 and -83 serving to hold theV glass runways. The' window sash frames comprise the bottom rail 73 formed of sheet metal and of suitable shape and bent to providel a pocket 74 for the reception of the glass l75 and the upper rail 76 formed of sheet metal is bent to form a pocket 77 which is of suitable extent in order that the glass 75 may be inserted therein and pushed upwardly until it passes the top 78 of the bottom rail 73 after which the glass can be lowered into the pocket 74, the position thereof being. best understood in Fig. 1. Connected in a suitable manner with the. top and bottom thereof are the -side rails of the. sash which comprise a. body portion formed of sheet metal bent to provide on one side a shoulder 79 extending outwardly beyond the wall 80 of the body and with the side member 81 provided with a suitable opening. v

8.2 'designates a `removable cap for the side rails bent to form a shoulder 83 and having a iiaiige 84 extending adjacent 4the wall 81 of the body when in position, said flange being also provided with an opening and through which and the opening in the member 81 passes a threaded bolt 85 which is secured in any suitable manner to the wall 80 ofthe body ,cf the side'rail. A nut 86 is the cap 82 in position. By this means it will be understood that by Vremoving the nut- 86 the cap 82 may be removed and the glass 7 5 inserted in position after which the cap 82 can be secured to the side rails, the shoulproperly in position.

87 designates al muntin bar which may be employed which consists ofthe body portion` formed of sheet metal bent to form the oppositely extending shoulders 88 and 89 andhaving'the flanges 90 and 91 extending angularly therefrom in suitable relation to each other.

A 92 designates a stiffening bar seated between the flanges 90 and 91 and said flanges i and stiifening bar are secured together by a split bolt 93 having the arms 94 and 95 extending on opposite sides of the flanges and having suitable openings 96 through which passes a screw or other fastening member 97 which likewise passes through suitable openings in the iianges 90 and 91 and the stiifening bar 92, for locking the parts together, 1t

beingnoted that the said bolt 93 is provided 4cap and the muntin' bar, it being noted that the oppositely situated shoulders 88 and 100 'and 89` and 101 serve to hold the glass in position.r By removing the nut 102 the cap can be removed and the glass 7 5 inserted in position.V afterwhich the cap may belagain secured in piace to properly hold the glass.

At suitable points in the top 29 1 provide pairs of openings 103 and 104 each pair being in suitable relation to a pulley 40 and through which the chain 105 passes one end being `connected with the top rail of one sash and the other end being suitably connected with the top rail of the other sash,

whereby it will be understood that when one sash is raised the other will be lowered. y

As will be seen in Fig. 1, I may it desired provide a turnbuokle 106 which is in threaded engagement Vwith the hooks 107 one of which is suitably connected with the chain 105 and the other of which is suitably connected with a top rail of thewindow sash this 'device being lused for regulating the length of the sash chains when adjusting the sashes.`

in some vinstances I have found it desirable Yto employ an adjustable wind shield for the windows and for this purpose 1 have provided a quadrant 108 which is connected with the side jamb of -the window iframe and which has a slot" 109 in which moves a clip 110 which carries a set'screw 111 for locking the clip in its di'erent positions. Pivotally connected with the sill is a. 'frame 112 which as shown carries'a glass 113 and which is in suitable connection with the clip 110 in order that the `trame andV glass can bemoved to opened or closed position, as desired. The upper end of the frame 112 is provided with a flange 114 which when the sash is correspondingly raised will abut against the same, as seen in dotted lines, Fig. 2, to prevent passage of any air.

It will nowbe apparent that I have devised a metallic Window by means of which the parts can be shipped from the place of their manufacture to their destination inv knock-down condition and can be readily andy quickly assembled at the. building and the sash frame can be immediately removed as desired. The novel construction of the side rails and muntin bar of the window sashes provide a'construction by meansof which the window glass can be inserted and removed as desired. v

lt will now be apparent that l have devised a novel and useful construction of a metallic window which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While I have, in the present instance, shown and described a preferred embodiment thereof which Will give in practice satisfactory and reliable results, itis tobe understood that the same is susceptible of modification in various particulars Without departing from the spirit or scope of the invention or sacrificing any of its advantages. C
